Our Galactic Center: A laboratory for the feeding of AGNs?
Susanne von Linden, Peter L. Biermann, Wolfgang J. Duschl +2
We demonstrate that our Galactic Center, despite little evidence for the presence of a currently active nucleus, provides insight into the feeding of AGN: The observed velocity fie…
The emission spectra of radioweak quasars. I. The farinfrared emission
Martina Niemeyer, Peter L. Biermann
We model farinfrared (FIR) spectra of radioweak quasars with the assumption that the emission is from heated dust, and that the heating is due to the central engine via energetic p…
Molecular Clouds Close to the Galactic Center
Peter L. Biermann, Wolfgang J. Duschl, Susanne von Linden
We demonstrate that the accretion disk model for the Galactic Center region by Linden et al (1993a) is applicable for at least one order of magnitude in radius from the Galactic Ce…
Cosmic Rays, II. Evidence for a magnetic rotator Wolf Rayet star origin
Peter L. Biermann, Joseph P. Cassinelli
Based on 1) a conjecture about the mean free path for particle scattering in perpendicular shock geometries, and 2) a model for Wolf Rayet star winds, we argue that explosions of W…
Cosmic Rays, III. The CR spectrum between 1 GeV and 10^4 GeV and the radio emission from supernova remnants
Peter L. Biermann, Richard G. Strom
We develop a theory to account for the cosmic ray spectrum between 1 GeV and 10^4 GeV following the earlier papers of this series. We use the basic concept that the cosmic ray part…
Cosmic Rays IV. The spectrum and chemical composition above GeV
T. Stanev, P. L. Biermann, T. K. Gaisser
Using the concept developed in earlier papers, that the cosmic rays originate in three different main sites, a) the normal supernova explosions into the interstellar medium, b) the…
